Title: backfire at idle
Post by: shmed on March 18 2012, 12:37:17 PM

ok guys got the wiring the way i think it should be.   everything lites up,  turns over , fires up an while its running its also backfiring,   would this be the cam sensor?  everything is stock chip injs everything.

Quite possible - have you checked the cam sensor setting?

Spark plug wires in the correct order?

start with the plug wires...

Then make sure the cam sensor is not 180 out, or one position out on the setting....
